Basic alarm with R2 sounds great for merch and fans or kids that need a cheeky r2 start to the day. You cannot set this alarm mon-friday has to manually turned of. There is no built-in battery and runs of USB – unfortunately, the connector is a Tpye A USB type Micro B instead of a standard USB-C – so for on going use you will need a adaptor for the wall or a 24/7 powered USB A to run this clock.
